It never ends, why would it?!?!

What cam did you go with?

What cam he says...

I haven't looked yet.

Im inclined to keep the stock one. It has the most LSA. Better idle and lower end power.

Ive had good luck with just intake exhaust and head work. Raising the compression really wakes these industrial engines up.

Hey WTR. I have built several of the predator 212's. For carburaters I have used genuine Makunis, the popular 22mm Chinese knock off, and the rejetted stock carburetor. For all out top end speed the slide type carburater will give you the most. But for crisp neck jerking acceleration the rejetted stocker wins hands down. Do your head work, raise compression ratio, a header pipe exhaust, and one of those free flowing air filters. I am at ( or very close to ) sea level. A .036" main jet and a .019" or .020" pilot jet, and she will leap out of the hole. I have run before and after scenarios with built engines on both a kart and on a mini bike.
Both vehicles had either 18" or 19" tires and 30 series torque converters.

Im at 4200' . My jetting will be different.
This was supposed to be a low budget build.

Make it reliable then give it to the wife unit.

Or unit wife as the case may be.

Well then a .034" or a .035" will be what you need. Jets are pretty cheap. Like about $3.50 each. I think that qualifies as low budget. I'm just trying to prevent you from blowing a bunch of money on a trick slide type carburater that will not leave the line as hard as what's on there right now. The pilot jets are real easy to drill out if you have a set of the micro drills.
